Subject: [PATCH v2 1/6] x86: add kconfig symbols for assembler VAES and VPCLMULQDQ support
Date: Fri, 29 Mar 2024 01:03:49 -0700 [thread overview]
Message-ID: <20240329080355.2871-2-ebiggers@kernel.org> (raw)
In-Reply-To: <20240329080355.2871-1-ebiggers@kernel.org>
From: Eric Biggers <ebiggers@google.com>
Add config symbols AS_VAES and AS_VPCLMULQDQ that expose whether the
assembler supports the vector AES and carryless multiplication
cryptographic extensions.
